To @ZZ whom it may concern:

Be it known that we, VELO HoULE and ABRAM W. KONKLE, citizens of theUnited States, residing, respectively, at Muskegon and Manistee, in thecounties of the same name and the State of Michigan, have invented a newand useful Improvement in Street-Sweepers, of which the following is aspecification.

This invention relates to street-sweepers comprising a brush, vareceptacle, and a conveyer, and relates especially to means forconnecting a frame carrying the brush and con veyer to,thedirt-receptacle.

The invention consists in providing a tank mounted on wheels, a wheeledpivotallymounted frame having a brush at its rear end, and a pivotedvertically-adjustable tongue for connecting the frame and tank.

In the accompanying drawings, Figure l is a side elevation of thedevice.. Fig. 2 is a plan view. Fig. 3 is a plan view of the brush andiframe, the conveyer being omitted. Fig. l is a section on the line 4L Aof Fig. 3. Fig. 5 is a detail view of the forward end of one side of thebrush-carrying frame, a lever being shown in section. Fig. 6 is a detailpers ective view of a coupling-plate. Fig. 7 is a etail of an end of atongue. Fig. S is a transverse section through the tank. Fig. 9

is a section through the tank at right angles to the section shown inFig. 8.

In the drawings, A represents a tank having a sectional hinged bottom Aand a crosspiece adjacent the bottom A-shaped in crosssection, as shownat A2, to cover the space between the two bottom sections A.

A shaft B is transversely journaled on the tank and carries a drum B, onwhich bears a lever B2.

A chain O passes over the lever and over one side of the drum and issecured at its ends to eyes O, secured to the bottom sections.

A chain B3 is connected at one end to the upper end of the lever B2 andat the other end to the iront edge of the tank A.

A seat A3 is provided on the tank and also il'anged side extensions A4.

Suitable axles D are connected to the sides of the tank, and on theseaxles are mounted wheels D.

On the rear of the tank is secured a couprated horizontal lugs E', and atongue E2 is provided at its front end with a flange E2, which'iitsbetween the lugs E and is pivotally connected thereto by a coupling-pinof the usual kind.

A frame F is pivotally mounted upon an axle F, and this axle is providedwith wheels F2.

In advance of the axle F the frame F carries a shaft Gr, to which therear end of the tongue E2 is pivotally connected.

On one side of the frame F and slightly projecting in advance of theframe is a rackplate H, provided with rack-teeth H. A lever H2 engagesthese teeth and is pivoted to the Jfront end of the frame F adjacent theside opposite the rack-plate H. This lever is connected by a link H4 tothe tongue E2 and is held in engagement with the teeth H by a spring H3.

Adjacent the rear end of the frame F is mounted a brush J, journaled inthe frame, and the rear end of the frame F is supported by small wheelsK. Y

A conveyer L is mounted on the axle F and conveys the sweepingscollected by the brush J to the tank A.

To drive the conveyer andi'brush, we form pulleys L on the inner sidesof the wheels F2. A belt L2 runs from one of these pulleys to a pulleyL3, carried at one end of the brush J, and from the remaining pulley L abelt L4 runs to a pulley L5, carried by a shaft or roller of theconveyer L.

The operation is as follows: By swinging the lever H2 the frame F ismoved vertically at its ends rocking on the shaft F and bring ing theroller J into contact with the ground or elevating it, as may bedesired. When the sweeping operation is completed or the tank A isiilled, the tongue E2 is uncoupled from the plate E and the tank drivento the dump.- ing grounds. The chain B3 is unhooked from the front ofthe tank A and the hinged bottom permitted to open, the sections Afalling downward and away from each other, thus dumping the load. Thesections are closed again by drawing on the lever B2.

It will be obvious that in use it is preferable -to incase the brush Jand a portion, or even the entire casing, in a suitable boxing or hoodto prevent dust from flying; but we have omitted any casing from thedrawings ling-plate E, provided with parallel perfol to more clearlyshow those parts which we IOO .consider neW, the construction of thecasing being optional.

Having thus fully described our invention, what We claim as new, anddesire to secure by Letters Patent, is-

1. A device of the kind described comprising a tank, a tiltable frame, asweeper carried by the frame, a conveyer carried by the frame adapted todischarge into the tank, a pivoted tongue carried by the frame, a leveradjustable vertically on the Jframe, means for locking the lever in itsadjusted position, connecting means between the tongue and lever, andmeans for detachably securing the free end of the tongue to a Xed pointon the tank.

2. In a device of the kind described, a Jframe pivotally mounted upon asupportingaxle, a shaft carried by the frame, a tongue pivotallyconnected to the shaft, a tank, zo means for connecting the tongue andtank, a rack-plate having teeth carried by the frame, a lever pivoted tothe Jframe and engaging the teeth of the rack-plate, a link connectingthe lever and tongue, a brush carried by the frame, and a conveyersupported on the axle and discharging into the tank.
